Thrombosis of popliteal artery pseudoaneurysm by deployment of angioplasty balloon after total knee arthroplasty.

We describe a case of a popliteal artery false aneurysm after total knee arthroplasty successfully treated by deployment of an angioplasty balloon across the aneurysm neck resulting in thrombosis.
